A Prediction

At one time, you could not talk in a library.  Time passed and talking quietly was allowed, but you could not use a cell phone.  Now you can talk as loud as you want, in the library, and there are signs permitting the use of cell phones.

My prediction?  One day I will be reading a book in the library, and someone will approach me and say, "Excuse me, but could you not read that book?  I'm trying to talk on my cell phone."
